Description

Technical Field

[0001] The utility model relates to the technical field of atomizing devices, in particular to a paint atomizing rotary cup. Background Art

[0002] The rotary cup is a special component for applying paint liquid in automatic painting equipment. The rotary cup is the most important component of the rotary atomization device. The rotary cup can atomize the paint liquid into extremely fine droplets. However, when the rotary cup of the existing rotary atomization device is used, the paint liquid formed has a relatively single shape. The rotary cup needs to be used for many different paint liquids and usage areas. A single rotary cup cannot meet all the requirements of the rotary cup characteristics. Therefore, different paint droplets cannot be formed according to different needs, which reduces the practicality and makes it inconvenient to use. Utility Model Content

[0013] The beneficial effects of the utility model are as follows: the paint liquid flows from the nozzle of the atomizing device to the inside of the rapidly rotating bell body, and the centripetal force causes the paint liquid to flow through the gap between the rotating disk and the distribution disk. In the internal cone of the bell body, the paint liquid will be evenly distributed and flow to the inclined surface. On the inclined surface, the paint liquid will separate from the inclined surface and be atomized into fine droplets. The edge of the inclined surface can be smooth, and the tooth groove can be single serrated or cross serrated, so that different paint droplets can be formed according to different needs, thereby improving practicality and making use more flexible.

[0019] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all of the embodiments.

[0020] Reference Figure 1-Figure 4 As shown, a paint atomizing bell comprises a bell body 1, a shell 2 and a rotating disk 3. The bell body 1 is a trumpet-shaped structure. The bell body 1 comprises a shell 2 and a rotating disk 3. The edge of the rotating disk 3 is connected to the inclined surface 4 through an arc surface 5, which is convenient for cutting on the arc surface 5. The edge of the inclined surface 4 is provided with a plurality of serrated tooth grooves 10 distributed in an annular shape. A hollow pin 6 is provided below the rotating disk 3, and an air ring 7 is provided outside the hollow pin 6.

[0021] The spacing D between the tooth grooves 10 is 0.194, the diameter L from the lowest point to the highest point of the tooth groove 10 is 1.083, and the angle α of the tooth groove 10 is 79.49° (refer to Figure 2), the edge of the inclined surface 4 can be smooth, the tooth groove 10 can be single serration or cross serration, so as to form different paint droplets, the outer ring of the hollow pin 6 is provided with an external thread 11, and the bell body 1 can be screwed onto the shaft of the bearing unit using the external thread 11, a partition 8 is provided between the hollow pins 6, and a guide hole 9 is provided on the partition 8 to facilitate the discharge of the paint liquid, a cavity 12 is formed between the shell 2 and the rotating disk 3, a groove 13 is provided between the air ring 7 and the hollow pin 6, and the bell body 1 is made of pure titanium, which has the effect of corrosion resistance and high temperature resistance.

[0022] Or the bell body 1 is composed of 2 semi-finished products, which are laser welded and then polished until there is no trace of secondary welding on the product, and the dynamic balance is maintained. The dynamic balance standard is G6.3, and the error is less than or equal to 4.5 mg (the swing value of 70,000 revolutions per minute, according to the G6.3 balance level, is converted at 70,000, and must be balanced to within 4.5 mg).

[0023] Working principle: When the device of the utility model is in use, the paint liquid first flows from the nozzle of the atomizing device to the inside of the rapidly rotating bell body 1, and the centripetal force causes the paint liquid to flow through the gap between the rotating disk 3 and the distribution disk. In the internal cone of the bell body 1, the paint liquid will be evenly distributed and flow to the inclined surface 4. On the inclined surface 4, the paint liquid will break away from the inclined surface 4 and be atomized into fine droplets. The tooth groove 10 can be single serrated or cross serrated, so that different paint droplets can be formed according to different needs, thereby improving practicality.
